100ml of water has a mass of BLANK Correct Answer 100g
A 100ml solution contains 10% (m/v) NaCl. What is the mass of
the NaCl? Correct Answer Total volume = 100ml
Total mass = 100 g
10% of 100g = 10g
A BLANK is a ratio of a solute's mass to the solution's volume
expressed as a percentage. Correct Answer mass-volume
percent
